You might try uninstalling all the USB devices under Universal Serial Bus Controllers in Device Manager and restarting the computer. (No USB devices connected until afterward, of course).

Windows will reinstall all the drivers again on start up, correcting any driver corruption, if any exists that cause this issue.
